っている。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a titanium oxynitride powder having a black tone. Currently, black pigments include carbon black powder and triiron tetroxide powder. Carbon black powder has excellent blackness and coloring power, but it does not mix well with resin, is extremely bulky and difficult to handle, and, although in very small amounts, may contain carcinogenic substances derived from raw materials depending on the manufacturing method.
Since it involves 4-benzpyrene, its safety has become an issue.
また、他の顔料に比らべ、比表面積がはるかに大きいた
め、他の顔料と混合して用いると、不均一な分散になり
やすいなどの欠点がある。Furthermore, since it has a much larger specific surface area than other pigments, it has drawbacks such as non-uniform dispersion when mixed with other pigments.

Ｆｅ２Ｏ３へ酸化される。Triiron tetroxide powder has agglomeration due to magnetism and has poor dispersibility. It also has poor heat resistance and turns brown at around 150℃ in the atmosphere.
Oxidized to Fe2O3.

h>-1 (14n≦10), which is obtained by reducing titanium dioxide powder with Ti powder or H2 gas at a temperature of 1000°C or higher, but sintering and particle growth are significant.
There is a fundamental problem in that the particles become coarse particles (1.0 pm or more) that are unsuitable for use as pigments.

積をも変化させることができる。When the inventors reacted titanium dioxide with ammonia, they obtained an oxynitride, which, as the composition changed,
It varies from black, blackish brown, blue-black, purple-black, and blue-gray, and like the white pigment titanium dioxide powder, the disadvantages of conventional black pigments are compatibility with resin, dispersibility, heat resistance,
Excellent safety. Further, the specific surface area can also be changed depending on the manufacturing conditions.

着色材、化粧基材として好適である。In particular, since it does not contain any harmful substances, it is suitable as a coloring agent for plastics for food and beverages and as a base material for cosmetics.

本発明の酸窒化チタンの酸素、窒素の含有量は反応の温
度、時間、ＮＨ３流量、ＮＨ３圧力、等によって変化す
る。The content of oxygen and nitrogen in the titanium oxynitride of the present invention varies depending on the reaction temperature, time, NH3 flow rate, NH3 pressure, etc.
反応温度は５５０°Ｃ〜９５０℃ の範囲が好ましく、
５００℃ 未満では反応が進まず、青灰色となる。９５
０℃を越すと粉末の焼結が著しくなり、粒子が粗大化し

、ＮＨ３の圧力については、常圧でも、充分に反応が進
行し、黒色粉末が得られるが、２〜３ ｋｇ／ ｃ ｍ
２Ｇに加圧することによって、反応速度は大きくなり、
しかも、窒素含有量が増加するため、黒色度の大きな粉
末が得られた。The reaction temperature is preferably in the range of 550°C to 950°C,
If the temperature is lower than 500°C, the reaction will not proceed and the color will turn blue-gray. 95
If the temperature exceeds 0°C, sintering of the powder will become significant, the particles will become coarse, and the pigment properties will deteriorate.At 0 reaction time, the reaction will proceed sufficiently even under normal pressure with regard to temperature, NH3 flow rate, and NH3 pressure. A black powder is obtained, 2-3 kg/cm
By pressurizing to 2G, the reaction rate increases,
Moreover, since the nitrogen content increased, a powder with a high degree of blackness was obtained.
原料となる二酸化チタン粉末については、粒子が小さい
（比表面積が大きい）はど、処理時間は短く、黒色度の
大きい粉末となった。Regarding the titanium dioxide powder used as the raw material, the smaller the particles (the larger the specific surface area), the shorter the processing time, and the resulting powder had a higher degree of blackness.
